#innovus 脚本命令

本文档详细介绍了如何使用ecoAddRepeater脚本命令在Innovus中针对最大转换延迟问题进行缓冲器插入。通过查找STA报告中的最大转换延迟违规者，选择受影响的网并定位缓冲器的位置，从而改善设计时序。

插buffer命令补充：（精准打击）
-term：指定对哪个pin插buffer
-net ：指定buffer插在哪条net上（当pin对应多个net时，-net可以指定）
-relativeDistToSink x : x为0-1的数字，数越小越靠近输入pin，0.5表示插在net中间

if inputin : tool add buffer in the middle of the net;if output pin : tool add buffer in the location of the inst which has the pin
